| Research Abstract |
The inverse Compton scattering(the photon-electron elastic scattering) is one of the most fundamental reactions which have a variety of applications to the quantum transport phenomena in astrophysics and cosmology. They are, for example, (1) the inverse Compton scattering of cosmic microwave background photons from electrons in galaxy clusters which makes the distortion of the spectrum(the Sunyaev-Zeldovich effect), and (2) the radiation mechanism of high-energy gamma-rays from supernova remnants. In the present research project, we have made theoretical investigations on these two subjects by solving the quantum transport equation of the cosmic microwave background photons and electrons both analytically and numerically.
